Venus Transit Egress as Seen by SDO's HMI Instrument
Egress close-up of Venus transiting across the face of the Sun. This image was taken June 6, 2012 as the transit was concluding by the Solar Dynamics Observatory (SDO) Helioseismic and Magnetic Imager (HMI) instrument on-board.
The HMI is an instrument designed to study oscillations and the magnetic field at the solar surface, or photosphere, and observes the full solar disk at 6173 angstrom with a resolution of 1 arcsecond. HMI is a successor to the Michelson Doppler Imager on the Solar and Heliospheric Observatory.
